My 7.3 leaks oil everywhere I go. There are drops on the ground after I shut the truck down. It looks like it's dripping from above the starter down to the starter, along the starter to the lowest place witch is the the exhaust.

 

I have replaced the passenger side valve cover gasket but have felt around it and there is nor oil.

 

By design if anything leaks into the valley pan it drains out the back of the engine over the starter.

So look @ injectors and lines, CDR & seals, oil pressure sending unit/switch, turbo and lines if turbo equipped, & IP.

 

Only thing I can think of is the oil sending unit. I put a mechanical Gage on there and seald it but may of came loose. I have a rdt and the fuel system looks normal.

 

is it your RDT? Im guessing the lack of vacuum in the crank case from the lack of CDR is making things leak. Pretty common issue, most know to keep the CDR. If i unhook the CDR tube i lose about a quart every 10 miles through the various leaks, CDR hooked up, no leaks.

 

After I installed the rdt it hasn't leaked a drop of oil untill just a few days now. I have had a rdt installed for the past 4 months.

 

i didn't poke holes in the valley pan under the turbo drain when installing the turbo on chip truck.leaky engine until i got back in there and punched some holes.dry ever since.i dunno if your turbo or n/a.good luck.


edit,oh man almost forgot..........lets go pats!

 

I am N/A. I think I might dye my oil and drive the truck untill it drips and follow the oil with a uv light. My brother thinks it might be the rear main seal.

 

If it was the rear main it wouldn't be on the starter.

 

So I have added oil and put some dye in the oil. I used degreaser on the the engine and sprayed it down with water. So far I have not had any oil drip on the ground. I think the truck only leaks when it's low on oil.
